Concrete Resurfacing - How To Fix Spalled Concrete

[@T.E.P.]

Another great vid ... just poured 85 sixty pound bags in an old basement (about 4 inch thick) and had to form it out in sections of 15 bags each. One section i was tooo exhausted and poured too much water and over worked the surface and that section had a few large areas of dusting. Used pure portland as a paint after cleaning off the dusty surface as much as possible to prime the surface after I wet the concrete. It came out fine so far. Wish i saw this 1st!! Thanks again for your informative vids.

[@MikeDayConcrete]

That sounds like hard work Thor. Good for you!!

[@boyshanks]

Excellent video! This is exactly what I was looking for. 👍👍

[@michaelcraig7297]

Very helpful video. I will use a lot of this info in re-surfacing my own patio.

[@MikeDayConcrete]

Awesome! glad I could help.

[@johnDoe-fg5qy]

2 variables that could improve results. Prime seal the raw concrete after grinding or mist the concrete so the resurfacer does not lose all moisture too quickly, allowing your broom finish to be smoother and the bond will be better. Prime sealing will also give you better color uniformity. After a resurface, you should seal the new concrete for added protection from stains and weather.

[@actionhiro4222]

Thanks for making this Video.

[@CSM-68]

Thanks for the video. Have a concrete driveway where the ice melt spalled in small sections. Can you repair the spots or do you have to resurface the entire driveway? I know all jobs are prices specifically, but what would be a general cost of the patio you did in your video?

[@shortvids6547]

Looks good, I will look into renting a grinder. You mentioned it was likely originally sealed poorly, do you need to do something after refinishing to seal it correctly?

[@Mikeeg0607]

Would this be durable enough to use in a garage with cars driving over it? The concrete in mine is badly spalled and very dusty

[@jaimeochoa6414]

Great channel. Very informative!

[@MikeDayConcrete]

Thank you Jaime!!

[@nikond90]

Is spalling caused by finishing concrete when it has already start to dry?

[@postmodern9208]

Not every day you hear the Wizard of Oz narrate a concrete video.

[@kennyamend3542]

HONESTLY thought my ear buds went to crap on me..

[@santiagogonzalez2710]

What do you use for resurfacing now mike i dont see they are selling the ardex brand anymore what would u recommend at big box stores?

[@chorgzent.3978]

Great video bro no cap

[@freemason4979]

I do the same + pressure clean. How does it hold upp after 5-10 ears? What about frost/thaw x20...

[@cathalrooney9409]

Great video Mike !

[@MikeDayConcrete]

Thank you

[@wakeupamerica2971]

Thanks for sharing. Just as many Q's answered in the comment thread as in the video. Appreciate the knowledge.

[@MikeDayConcrete]

Glad it was helpful!

[@kennyamend3542]

Great Video

[@MikeDayConcrete]

Thank you!

[@willieking4306]

Is any update on this one. I am resurfacing with Cement All to my side walk in ny. What products can you suggest?

[@crazyhandshands9028]

Question Mike can i use bonding agent and Portland cement together because Portland is a really good product.

[@MikeDayConcrete]

That won't work, you need a repair product designed to go on this thin.

[@gabygol70]

Is there a different concrete colors or does one bag come with Color I just don’t want to buy a bag and it does not match the same color as my patio

[@MunkieFeet]

Hi Mike, I plan on using this for a 9x12 garage floor that I finished Diamond grinding. Can epoxy paint go on top of Ardex?

[@MikeDayConcrete]

Yes you can!

[@mikegresham9424]

How long does it last

[@davidmueller790]

Hey Mr. day, Is it OK just to resurface sections of a driveway. Just asking because I didn’t know after using the Ardex if it will match the other parts that I wasn’t going to resurface?

[@Niko-iq8bc]

No would not recommend at all just rip it out and do new it’s concrete not asphalt

[@oh-bc8cr]

It will hold up we use this where semi trucks pass on and it holds up good but it has a different color to concrete which is why it's best to the whole square unless you don't care about the colors then you could do sections but it will hold up for a while I use this material EVERYDAY at work

[@imariosf]

Can I use Ardex CD to level some concrete pavers before resurfacing? When should I use a corner edger to clean up up edges?

[@247KW]

Mike i have a horrible cracked parking pad into the garage. If I pressure wash the concrete extremely good, plus remove loose material, could I mix this up to fill in all the gaps/cracks? Then come back and resurface it all without grinding? Its so bad....like cracks everywhere but I can't afford to replace it

[@oh-bc8cr]

Open the cracks more probably half an inch with a grinder and a cutting blade clean them out and then put Pegabond in the cracks, let it dry and then do this video exactly how Mike did it and that should do it

[@haydenglaser5292]

Can u use Portland and sand

[@MikeDayConcrete]

No, I don't recommend that. It doesn't bond as good.

[@kevinbriggs2611]

Does ARDEX come in a tan or beige color?

[@fortyoddyears5295]

Can you dye and/or polish this if this were used to repair the surface inside the home?

[@dustinfancher]

I've got some concrete that was poured in the 70's I'd like to resurface. Would pressure washing and letting dry also suffice to prep the surface?

[@mikemiceli6122]

Do you need to use any type of bonder?

[@Gforu81]

Wish your business was near me 😩 desperately need this

[@oh-bc8cr]

Are you in southern California?

[@oh-bc8cr]

I literally just started doing this as a business In the southern California area

[@stuartfarrell6729]

could you use this to stamp

[@TheSeancassady]

Would be curious to see how this holds up a year or two down the road.

[@kurtfrancis4621]

That's all it's meant for.

[@oh-bc8cr]

It holds up we use this on roads where nothing but trucks drive on it and it's been good for like 7 years also this ardex CP is good to patch holes in concrete walls it's sticks very good and doesn't crack

[@jonesieism]

I’d love to see what this looks like now

[@sevn8757]

So if i have only a small amount of it do i still need to do tbe whole slab?

[@MikeDayConcrete]

No, you can just do small areas. It'll just look like a patched area but still works the same. I do the whole area to make it look like new again.

[@pensive69]

Mr. Day is there any manufacturer's suggested curing procedure for this fast cure product? You didn't seem to mention it. Some of the other toppings i have experience with say water spray or moisture during the short cure period.

[@MikeDayConcrete]

This is right from the Ardex Tech Data Sheet about curing "Although ARDEX CD requires no special curing procedures, avoid applying this product if rain is expected within 6 to 8 hours or freezing temperatures could occur within 24 hours of application. As with any cementitious material, these conditions can alter the appearance and performance of the dressing."

[@321watch]

With a whole driveway, some of which is not spalling, should the whole driveway be ground. Or just the spalled parts?

[@321watch]

Will the spalling occur again after next winter after prep,dress and seal. Will I have to do it every year

[@papalou190]

How long do you think that will last?

[@flavius220988]

Thank you very much for this. You've done a great job.

[@Geonious]

Can that product be used for deep spalling? My garage door entrance has some deep spalling (1/4" - 1/2") and the lime stone is showing.

[@mpsniper933]

Well done, Sir! Thank you for the video.

[@MikeDayConcrete]

My pleasure!

[@ricanbee2849]

Wow nice beat

[@TalksWithRyan]

Also does this stuff call for a concrete bonding agent?

[@kdublock]

No diamond grinders are available to rent in my location. Could a pressure wash work instead?

[@oh-bc8cr]

Just get a harbor freight grinder and buy a cup grindstone blade

[@kinterest1562]

What materials did you use?

[@benjibumble]

when do you pull the tape?

[@AA1234575]

What best way to get in contact with you regarding this? Happened to my patio and I’d like to show some pictures and get your opinion.

[@samerk4970]

can i call you with a problem solving on dyed concrete that is not finished right?

[@MikeDayConcrete]

email me @ [e-mail]

[@ensignj3242]

I’m really surprised that you don’t dampen the concrete before troweling the top coat.

[@blaster-zy7xx]

Correct. The slab should be moist, not dry.

[@moto960833]

The Ardex CD instructions say not to pre wet the slab

[@FunkDitch]

Will this material hold up in a garage? I want a smooth finish and I’d like to apply an epoxy afterwards. Road salt is ruining my garage floor

[@MikeDayConcrete]

Mark, if you need to repair your garage floor, search for my crack repair videos. That's what we use to repair spalling, cracks, chips and more on garage floors before we epoxy them. The product is called CrackWeld

[@stevewaclo167]

Will Ardex survive on a driveway with a diesel pickup on it?

[@MikeDayConcrete]

If it 's done right it will.

[@stevewaclo167]

Mike Day Everything About Concrete, Thanks. Reno contractor scheduled to visit for an appraisal.

[@oh-bc8cr]

Yes it will ,we used this material for a driveway that diesel semi trucks pulling heavy loads drive on and its been holding up for 5 years so far

[@pumas2288]

Is this Ardex CD and Cemental doing the job?

[@Brandon-no3vc]

How long will that last

[@splash5974]

Man that porch looks dead level! Could the fact that there's not enough slope have lead to the spalling? Must take along time for water to evaporate off that surface... Great vid!

[@jamesyman007]

Hey mike can you use that on steps(mainly in the vertical)?

[@boyshanks]

Yes using a hopper.

[@kimbanyc]

How do you make it more of a sand color?

[@MikeDayConcrete]

I've never tried to color this stuff but you could get some liquid tint from Direct Colors and try their sand one.

[@bellagio88]

Mixing cement with a concrete mixer

[@kimsanfilippo8429]

Do you have to do the whole slab or can you do a partial repair? Is it possible to feather to the edge?

[@jacobc6087]

Yes you can feather it in

[@oh-bc8cr]

The colors won't match

[@cleeotus]

How long will this last on a driveway in northern Indiana?

[@cleeotus]

And are you able to and/or would you suggest sealing when done?

[@MikeDayConcrete]

If done with proper prep, and proper application, it should last a very long time.

[@MikeDayConcrete]

Yes, sealing is always good.

[@craftman5632]

Wouldn't it help if the slab was slightly wet.

[@MikeDayConcrete]

That does help. It rained the night before so I didn't want to add any more moisture to it.

[@InquiryTeaching]

Ardex recommends that the concrete is very clean, either through grinding or pressure washing. When the material (Ardex Cd) is applied however, the substrate is recommended to be completely dry.

[@shazmir4021]

Hi Mike, can you fix my concrete? Where are you from ?

[@stevenforrester1124]

Do you have to broom finish ?

[@shortvids6547]

In cold climates texture is preferable to prevent slips.

[@calvinkey526]

The concrete patio at my friend's house is far worse than this. There is so much concrete in their back yard area that is in really bad shape. I'm not sure if it can be salvaged but any tips would be much appreciated

[@oh-bc8cr]

Open the cracks more probably half an inch with a grinder and a cutting blade clean them out and then put Pegabond in the cracks, let it dry and then do this video exactly how Mike did it and that should do it 7:41

[@LuisMendoza-hk9dg]

Very nice for n.j I'm Mendoza concrete LLC

[@MikeDayConcrete]

Hi Luis!

[@amandamartinez6115]

We are planning to start our own concrete company, however, we are not sure how to make the contracts for a job. I have 10 years of concrete experience. I just don't have experience of Bidding nor contracts. Please Help. Also, do you charge your projects by the sq ft or by the job?

[@MikeDayConcrete]

Charging for projects (floors, slabs, stamped concrete, staining concrete) is done by the sq. ft. Smaller projects like 500 sf or under is done by the job with a minimum charge for labor. Bidding is so different around the US, I'm not sure what people charge where you live. Start by figuring your materials then what you need for a minimum per day for labor to make a profit.

[@amandamartinez6115]

@@MikeDayConcrete Thank You for your advice. What are your thoughts on the Medusa Walking Saw? Also, would you happen to have an example contract you could show us? We live in Wyoming and we still have a lot of snow on the ground. We are waiting for it to warm up some more the ground is still frozen.

[@cheshstyles]

@@amandamartinez6115 check out the nextdoor app. (It is like facebook for your neighborhood) I get a lot of small jobs off that. And the beauty of it is, they are all in my neighborhood so it's super close and easy to build reputation. Also: craigslist, meetup (u can approach real estate groups etc. and see if someone will let you do a small job for a decent price to get to build relationships) or check with local remodelling companies, they frequently do not do their own concrete work. Also: facebook!

[@TalksWithRyan]

What would a person charge to repair something this size? Is it still by sq ft ?

[@noemig04ify]

I know your not asking me, but yes in most occasions it is by the sq. I usually charge $2.00 a sq ft.

[@noemig04ify]

But due to higher prices the ardex is costing a little more here in Texas so some are charging a little more than $2.00

[@splash5974]

Mike, it sounded like you were giving your presidential speech infront of millions 😂🤣

[@leesschurr3791]

Will this work on a driveway? The concrete company who poured my driveway charged me $10,000. We did not park cars on the driveway for three weeks and did not use salt on the driveway. It started spalling within 6 weeks. I’m on a fixed income and cannot afford to have a new driveway poured. It’s a three car driveway. 😢😢😢😢

[@Tartinitone]

Funny how every book says spalling is from bad mix or overfloating, but every contractor says it’s the owner’s fault from salt.

[@MikeDayConcrete]

It can be from a wet mix and/or over floating. Also from using de-icers. Having a good contractor and properly informed owner usually takes care of this problem. Sealing the concrete is important also.

[@Tartinitone]

​@@MikeDayConcrete Hi Mike. Multiple factors to be sure. Here's a link to a picture of my driveway. The two sections were poured about a day apart and when contractors (original or consultants for repair) want to blame it on the one time I used salt, I have to be a little skeptical. It started to show signs of wear within months of installation and before salt was ever used. drive.google.com/file/d/1UHdVr_yM9FMIIeGFuHSfF5xJd39LcKi0/view?usp=sharing

[@InquiryTeaching]

Often, when called to customers homes with badly spalled concrete in the garage you can tell exactly where the cars sit as the drip the salty water off the cars. In the corners, and areas where cars do not drive, the concrete is often in great shape.

[@joniboulware1436]

I am in an HOA that spent over $300,000 replacing asphalt driveways with concrete. Two and three years later we spent $150,000 partially replacing concrete. We had it tested and the lab concluded it was overworked at the wrong time. But up to the lab report, everyone blamed it on salt or de icers and bad sealer. Even driveways that had no use over winter (second homes) spalled.

[@davegenter6849]

Thats a pretty ruff broom finish, how much did you charge customer?

[@rjb6327]

Hey Mike! What are you doing in a bucket? BTW: Can this product be used on a driveway skirt?

[@MikeDayConcrete]

Bob, I mixed the product in a bucket. Yes you can use it on a driveway skirt.

[@hollyhold562]

ARDEX?? Artex??

[@donaldloos2049]

You didn't wash it or bonding agent hmm?

[@MikeDayConcrete]

Donald - No, I lightly ground the slab to prep and clean, then vacuum. Ardex CD doesn't require a bonding agent.

[@donaldloos2049]

I would of at least washed it off , just to get that dust off . How does that shit hold up? I've had luck with t1000 overlay from Butterfield Products. Do a one year later video on that job , I'd like to see it lasts.

[@MikeDayConcrete]

Donald - this is from the Ardex CD data sheet : All concrete substrates must be structurally sound, solid, thoroughly clean and free of any form release, sealers or paints, patching compounds, dust, dirt, oils and any other contaminant that could act as a bond breaker. If necessary, mechanically clean the floor down to sound, solid concrete by shot blasting, grinding or similar. High-pressure (5000 psi) power washing may also be used to remove dust, dirt and debris, though the concrete must then be allowed to dry thoroughly before proceeding. I could have washed it off, but I only had a small window to get this done (Sunday) It's a place of business open 6 days a week. I didn't have time to let it dry out for a day before resurfacing it and Ardex doesn't require us to wash it or prep, grind and vac is good. I've had good luck with this product. I also use a lot of Butterfield products. We stamp a lot of concrete and use their integral color as well as their stampable overlay.

[@donaldloos2049]

It said it self free from dust , so your vacuuming isn't enough to get rid of dust . I totally understand time frame but if you washed it early am or Saturday evening ( if possible). I feel would of been better . Not hating just saying!

[@InquiryTeaching]

@@donaldloos2049 if you live close and want another trip back, and the weather is favorable, and the business is closed long enough, then washing it off wouldn't hurt. Specs are for application over dry concrete though. This product wears well and I have done gas stations with it before around the pumps. In northern climates, you should still seal it with a good sealer to prevent similar problems from occuring again.

[@tripjet999]

I'd cover the outer walls of the home up at least two feet high It's far too easy to splatter material onto the siding or glass. And good luck getting it off, once it's there. Parking lot asphalt should be taped off, too.

[@nvrbored1]

I'd say that damage is caused by fertilizer. Salt damage would be in front of the door & not off to the 2 sides. Good video though.

[@MikeDayConcrete]

No, it's salt damage.

[@InquiryTeaching]

Judging from the type of front door I would guess this is business with multiple parking spots and customers walking upto sidwalk at different places. Hence... salt spread over entire walkway.

[@ensignj3242]

Every vid I’ve seen said to wet co Crete first

[@MikeDayConcrete]

Depends on the product you're using. Ardex doesn't want you to wet it first.

[@charlesviner1565]

👍

[@MRM-wp4gr]

Your broom finish is too ruff....I hate that rough of a texture on concrete. I would let it dry a little more and then use a finer broom for a nicer look

[@MikeDayConcrete]

You can't let this product dry more, you have to broom it very quickly or you won't get the broom finish on it. I could use a finer broom though.

[@Niko-iq8bc]

I ain’t gon lie wtf is that. Never seen anything like this in my life. I get the customer is probably cheap but I would of told them the only way is to rip it out and pour new concrete. If they don’t like that then call someone else to do it
